To' all whom t may concern;

Be it known that I, SIMON W. WARDWELL,

Jr., a citizen of theUnited States, residingY at.

` tion.

My invention relates to that' class of winding machines whichareemployed for buildi ing up cops of the character illustrated in myUnited States Letters Patent No. 486,745, and

my invention consists in constructing the parts of the machine so as tosecure greater delicacy of adjustment and operation and to generallyimprove the character and efficiency of the machine as fully set forthhereinafter and illustrated in the accompanying drawings, in which-Figure 1 is an elevation in part longitudinal section of a windingmachine with my improvements; Fig. 2, an end view looking at the lefthand end of the machine, Fig. 1; Fig. 3, an end view of the opposite endof the machine; Fig. 4, a plan view of a detached part of the machine. vl

The frame A is suitably constructed to support the operating partsincluding a spindle ot and means for rotating it, a thread guide O,having an eye fr, and means for reciprocating the said guide andappliances for varying the relative action of the guide and spindle sothat at the end of each reciprocation the guide will occupya differentposition as regards the holder or cop; that is, it will be opposite apoint on the periphery of the cop back of or in advance ot the point towhich the guide was opposite at the rocaton.

As shown, the spindleu. is the end of the driving shaft 9 but any othersuitable form of support for a holder (solid or tubular) may be used. Asshown, the spindle projects from the side frame to receive a tubularholder 10.

The shaft 9 for rotating the holder is driven by a driving pulley 12receiving a driving previous recip- V, belt, turning loosely on theshaft 9, and having an inner beveled face to engage theouter beveledface ofv a clutch pulley 13 turning with but sliding on the shaft 9, thepulley 13 being pressed into `engagement by a spring' 15 and carried outof engagement byj'the downward pressure of a beveled projection 20 uponan arm 19 extending from a rock shaft 21, Whenthe said projection 20 isbrought against the beveled face of a collar 22 on the pulley. A spring18 t'ends to turn the shaft to throw downward the arm 19 and carry thepulleys out of engagement. A suitable detent is ernployed formaintaining the shaft 21 in position to keep theprojection 20 out ofcontact with the collar 22.` Thus the shaft 21 carries at one end an.arm 45 with a cross shoulder 46 that engages a cross shoulder 43 uponthe arm 42 of a lever E, thereby preventing the rocking ofthe shaft 2lunderthe action of the spring 18 so long as the shoulders 43, 46 aerengaged. A handle E secured lo the shaft 21 serves as a means of turningit by hand.

As the guide in this class of machines must be reciprocated veryrapidly, it has been i found that unless the guide is very light inWeight, the momentum from the rapid movement will tend to carry it outof position and interfere with thatA nice and regular operation which isnecessary in order that the thread as `it is brought to eachend of thecop may be laid across one of the preceding threads with a sharp bend,and carried back at one side of said preceding thread.` I thereforesupport the guide'on a carrier frame d, the guide being of very thinlight metal and sliding upon the frame which is of heavier. material andwhich is pivoted or otherwise supported so that it can be carriedoutward as the cop increases in size, it being necessary to theformation of a cop of the character desired to -maintain that portion ofthe guide which has the guiding eye in close contact With the copthroughout the entire series of operations of building up the cop. Thusthe guide in which is the guide opening :r consists of a thin blade ofmetal With an opening receiving a porcelain or other vitreous stud cinwhich is a notch coinciding with the guide opening While the framedconsists of an arm 4swinging on a stud 26 Iat one side of the mainframe, and an arm 5 swinging upon a hollow stud or sleeve 27 at theopposite side, and a cross bar 32 with a horizontal rib 34 receiving aguiding bracket 35 secured to the guide C.

A connecting plate `or rod 37 connects the lower end of the blade c witha slide 38, sliding in guides of the cross bar 32 and having a stud 40extending into the groove w of a cam wheel D, secured to a shaft 25extending through the hollow bearing or sleeve 27, so that the rotationof the shaft 25 and its cam reciprocates the guide during the rotationof the spindle and holder. As the spindle and its holder must be turnedgenerally two or more times to each reciprocation of the guide, theshaft 9 is rotated more rapidly than the shaft 25, and this is effectedthrough the medium of suitable and intermediate gears.

As shown,a grooved pulley F upon the shaft 9 carries a belt passing to agrooved pulley D' upon a shaft 2li, carried by an arm or frame 27swinging upon the projecting end of the shaft 25,'iwhich shaft extendsinto an opening arranged eccentrically on the hub of the framela weight33 depressing the outer end of the said frame so as to maintain the beltu taut to prevent any possible slipping.

A pinion 30 on the shaft 29 gears with a toothedlwheel 3l on the shaft25, and it will be seen that by the use of interchangeable gears 30, 3lot different diameters, the spindle a may be caused to revolve anydesired number of revolutions to each reciprocation of the guide, and anincrease in the number of windings between the ends ofthe cop does notchange the speed at which the thread is wound. As before stated,however,the spindle ot must revolve not only a sufficient nurnber of times toeffect the desired number of winds at each rotation of the guide, but itmust also have either a slightly less, or slightly greater, movement sothat a point on the cop which at the end of one reciprocation of theguide is opposite the eye of the latter, shall at the end of the nextreciprocation be a distance beyond or back of the eye of the guide equalto the distance between two adjacent bends following each other at theperiphery of the cop. In the construction shown, I secure this result bymaking one of the pulleys FRQ', of the belt gear an expansion pulley. Asshown, the pulleyJQy is the expansion pulv ley, consisting of a disk 79secured to the shaft 29 and having at one side beveled teeth 81, and asimilar disk S4 having beveled teeth 82 interlocking with the teeth 8lwith means for carrying the disks to and from each other so as toincrease or decrease the diameter of the channel in which the belt lies.A spring 83 tends to separate the disks,whilethey may be broughttogether against the action of the spring, by means of a nut 87 turningupon the threaded end of the shaft.

By adjusting the disks to increase or decrease the working diameter ofthe pulley D', it is not only possible to secure the added or decreasedmovement necessary to cause the thread of one coil to be laid over thatof the other, but it is also possible to secure that nice adjustmentnecessary to this end under variations of operations resulting fromdifferences in the characters of the threads, and from differentconditions of the same thread from variations in the atmosphericconditions.

In many instances, it is not practicable to procure cop holders or tubesthat are of regular shape as they are frequently flattened at one ormore parts or thicker at one end than at the other, and it has beenfound that when the guide is pressed against such irregular holders inbuilding up the cop, it will movein and out with the projections andrecesses are brought opposite to it and the cop will be started of anirregular shape which may have a tendency to magnify as the size of thecop increases. It has been found that this can be corrected by pressingthe guidetoward the cop and by permitting it to move freely outward asthe size of the cop increases, and also when any projection of anirregular character is brought beneath it, but by preventing the guidefrom moving inward after being thus forced out by a projection, and thatafter the first two or three layers of thread are wound, the cop willassume a regular cylindrical form. Any suitable means may be combinedwith the guide for thus permitting it to move outward but preventing itfrom moving toward the cop after it has been moved out ward to anyextent; but as shown in Fig. 2, an arm 60 extends from the guidecarrying frame d, and is provided with a stud 62 bearing upon theperiphery or eccentric face of an eccentric cam 64 which is pivoted toastud 66 and has a counter-Weight (58 tending to turn the cam in thedirection of the arrow so that when the frame d is swung outward to, anyextent, the cam tiltwill be turned to maintain its bearing with the stud62, thereby preventing the frame from swinging inward again. The arm -60is suitably weighted by a weight 6l:L hung thereto. As the frame@ swingson the same axis as that of the camfthe relative positions ofthe cam andstud 40 are not materially altered when the frame swings back.

The thread passes from the tension device E2 over a guide pulley 56 tothe eye of the guide C, and to arrest the motion of the machine if thethread should break, a stop actuating devicel of suitable constructionis used. As shown the said stop actuating device consists of a lever 5lhaving a long arm 52 extending outward and bearing upon the threadadjacent to the yguide roll 56. To the lever 51 is hung a wedge 53 withan inclined face bearing at one side upon a stud 57 on the frame, and atthe other upon a lug 55 on the arm 42 of the lever E. If the threadbreaks the long arm of the stop lever swings downward and the wedgeforces away the arm 42 of the lever E to carrythe shoulders 43, 46 ontof contact when the shaft 2l will be turned by the spring 18, and theclutch device will be unlocked, stopping the machine. Itis desirable inmany instances to prevent knotted threads from being wound onto the cop,and a knot-catcher J is therefore provided to operate in connection withthe stop device to arrest the motion of the machine whenever a knotapproaches the guide. The knot-catcher may be of any suitable character,as shown. It consists of IOS IIO

lIo

a lever 58, pivoted to a pin 6l at the end of the arm 44 of the lever Eand having at the opposite end a fork or notch through which the threadpasses toward the pulley 56. At the pivoted end of the lever 58 is a cam59, which bears against a bearing, as a set screw 63 extending through astud on the frame of the machine, and an adjustable spring 65 tends tohold the lever 58 against-any suitable bearing. When a knot upon thethread is brought against the lower edge of the lever 58, the latter islifted, and the cam 59 bearing on the screw 63 depresses theend of thearm 44 of the'lever E, rocking the latter and carrying the shoulder 43away from the shoulder 46 so that the stop motion is putinto operationto arrest the movements of the machine.
